Conservation status

edit

In November 2018 the Department of Conservation classified Hadopyrgus rawhiti as Nationally Critical under the New Zealand Threat Classification System.[1] The species was judged as meeting the criteria for Nationally Critical threat status as a result of it only being found in one location which was less than 1 ha in size.[1]
